Dynamic Application Security Testing

Definitions

1. Dynamic Application Security Testing is runtime testing of a running application by sending requests and observing behavior from the outside. Security teams use it to enforce trust, reduce exposure, improve detection, or standardize secure operations in production environments. Its value depends on correct configuration, lifecycle management, and surrounding controls, because weak defaults, poor integration, or missing visibility can create gaps that attackers exploit.

   In plain English: Dynamic Application Security Testing is a security concept or control that helps organizations protect systems, manage trust, and notice suspicious behavior before damage spreads.

   Example: "After the review, the security team rolled out Dynamic Application Security Testing in the affected environment, documented the operating procedure, and verified through logs and test cases that the control reduced exposure without breaking normal administrative or user workflows."
